When electrical issues arise, these quick receptacle power tests will come in handy.
Learn how to measure voltage, conduct a polarity test, and more.
Ever wonder whether power is reaching an outlet?
The voltage reading on a digital multimeter can tell you.
You conduct most of these tests with the power on, so work carefully.
What Is a Digital Multimeter?
It is sometimes also known as a multitester.
Costs vary from a few dollars to several hundred depending on how precise you need the measurements to be.
A basic handheld multimeter meant for non-professional, at-home use costs between $15 and $50.
How to Measure Voltage
Voltage is the amount of pressure that pushes the electricity through the circuit.
The higher the voltage, the more electricity is flowing.
To test it, set the multimeter to measure voltage.
Insert a probe into each slot and read the line voltage measurement.
A properly working outlet gives a reading of 110 to 120 volts.
If there is no reading, check the wiring and the outlet.
How to Test an Outlet
Before you begin,turn off the power.
Then disconnect the outlet from the wiring.
Set your multimeter to Ohms.
Put a probe into one of the outlet slots and the other probe on the nearest terminal screw.
The multimeter should indicate continuity.
Test the remaining slot and terminal.
Then test the ground slot to the grounding terminal.
Then, turn the power back on.
Touch a probe to the ground wire or the box and the other probe to the black wire.
If you get a reading, that is the hot wire.
If not, it is the wire leading to the other devices.
